In this study, recycled non-woven carbon fibers were successfully implemented as reinforcing filler material for reinforced material for functional parts in pressure vessels. Using recycled carbon fiber nonwoven efficiently and sustainably allows the reduction of the amount of new fibers used to the necessary minimum per component. Despite the high requirements on the material in carbon fiber reinforced pressure vessels, the fittings (endcaps/bosses) enable possibilities to integrate a significant amount of recycled material without reducing the design or performance capability. The integration of both, recycled and UD materials will be realized through a sandwich-like structure, wherein the recycled material fills the core while the load-bearing fabric layer serves as the outer shell. For this study, a tensile strength of 12.8 MPa in the machine direction and 17.4 MPa in the transverse direction was achieved using the resin transfer moulding (RTM) process for the finite element modelling and compared with the material properties from the vacuum assisted resin infusion (VARI) process.      «
